MGS-1000
The motor-generator experimental apparatus is a set of motors and generators connected directly to each other, and it is device that can show the principle of which motor’s power create the electricity by the generator. In addition, it is good practical equipment to learn measurement technique in laboratory to the engineers in charge of measurement who work with noise and mechanical vibration generated from the set.
